The U.S. Department of Homeland Security will use RFID chips on a trial basis to track the arrival and return of visitors from abroad. The testing phase, which will commence this spring and is expected to last one year, will occur at selected points of entry across the U.S., and it will complement the current U.S.-VISIT scheme. The U.S.-VISIT scheme, which has encountered criticism, entails fingerpriting visitors, and to date over 400 people have been refused entry or arrested as a result of this scheme. Although the exact way that the RFID chips will be implemented is not yet known, they will be used to track pedestrians and vehicles entering the U.S. Asa Hutchinson, U.S. Under Secretary for Border and Transportation said, "through the use of radio frequency technology, we see the potential to not only improve the security of our country, but also to make the most important infrastructure enhancements to the US land borders in more than 50 years."
